ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 460,739, dated October6, 1891.

Application filed June 25, 1391. Serial No. 397,515. (No modelfi To allwhom it may concern:

Be it known that I, SoLoN M. BOWMAN, a

' citizen of the United States, residing at Timscribed, and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view showing therunner of a corn-planter to which my invention has been applied. Fig. 2is a rear elevation of the same.- Fig. 3 is a vertical transversesectional View.

Like numerals of reference indicate like parts in all the figures.

The runner, which is designated by 1, is of ordinary construction, therear end being bifurcated to receive thelower end of the seedspout 2.

3 designates a vertically-arranged rod, the lower end of which isbifurcated, the arms 4 4 of said rod being connected by means of boltsor rivets 5 with the mold-boards or gage-plates 6 6, which are arrangedat the sides of the runner. The-upper end of the bifurcated rod 3 isscrew-threaded and is extended through a perforation in a bracket 8,which is mounted at the upper end of the standard of the runner. Thesaid bracket 8 is U-shaped, and it also serves for the attachment of theupper ends of a pair of rods 9 9, the lower ends of which are connectedwith the gage-plates 6 6 near the rear ends of the latter and extendedinwardly to form brackets 10, which rest against the sides of therunner, thus keeping the mold-boards or gage-plates 6 6 at a properdistance from the latter.

The upper ends of the rods Sandi are provided with nuts 11 above andbelow the U- shaped bracket 8 to enable the said rods to tion will bereadily understood from the foreygoing description, taken in connectionwith the drawings hereto annexed. Myimproved mold-boards or gage-platesmay be readily applied to the runner of acorn-planter of ordinaryconstruction, and by means of the said gage-plates the runner may beadjusted to run more or less shallow, thus depositing the seed to anydesired depth.

By my improvement the seeds are planted at a perfectly-uniform depth,regardless of the looseness or compactness of the soil, and yet,regardless of the depth to which'they are planted, to cover themuniformly. By this means a uniform germination takes place. All clods,loose stones, &c., are swept to one side, thus leaving a smooth trackfor the packing or covering wheel usually employed.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States 1. In a corn-planter, thecombination, with the runner, of a vertically-adjustable bifurcated rodstraddling the said runner, and the mold-boards or gage-plates connectedwith the lower ends of the arms of said rod, substantially as and forthe purpose set forth.

2. The combination, with the runner, of the vertically adjustablebifurcated rod, the mold-boards or gage-plates connected with the lowerends of the arms of the same, and the brace connected with saidbifurcated rod near its lower end and engaging the front edge of therunner, substantially as and for the purpose set forth.

The combination, with the runner, of the U -shaped bracket arranged atthe upper end of the standard of the same, the verticallyadjustablebifurcated rod mounted in said bracket, the mold-boards or gage-platesconneoted with the lower ends of the arms of said bifurcated rod, andthe rods connected with the rear ends of said mold-boards or gage-platesmounted adj ustably in the U- shaped bracket at the upper end of therunplates and having, laterally-extending lower nonstandard and havinglaterally-extending ends bearing against the sides of the runner, lowerends bearing against the sides of the substantially as and for thepurpose set forth. runner, substantially as and for the purpose Intestimony that I claim the foregoing r 5 5 set forth. my own I havehereto aflixed my signature in 4. The combination, with the runner, ofthe presence of two witnesses. Vertically adjustable bifurcated rod, the

1nold-boards or gage-plates connected with SOLON M. BOWMAN. the lowerends of the arms of said rod, and \Vitnesses: 10 thevertically-adjustable rods connected with J. M. CRABILL,
